No, it sure doesn't.

I tried

SET(CMAKE_REQUIRED_LIBRARIES "kernel32")

and

SET(CMAKE_REQUIRED_LIBRARIES "kernel32.lib")

as well as the unquoted versions in my previous post.


If it's worth anything, this simple program compiles and executes just
fine with no additional compiler flags or libraries.  Before I run
cmake I set up my environment by running the vsvars32.bat file located
in the Tools directory of the MSVC install.

#include <windows.h>


#include <stdio.h>

int main(int argc, char* argv[])

{

  fprintf(stdout, "sleeping.\n");


  Sleep(1000);


  fprintf(stdout, "done.\n");



  return 0;

}

TIA,
